A soda drink manufacturer uses machines to dispense ingredients into bottles that move along a filling line. The machine that dispenses soda drinks is working properly when 9 ounces are dispensed. Suppose that the average amount dispensed in a particular sample of 40 bottles is 8.91 ounces with a variance of 0.04 ounces. Is there evidence to support the hypothesis that the machine should be stopped and production wait for repairs? Set the Null and Alternative Hypotheses and reach a conclusion.
